CARL G'UGGENBUEHLER, or NEWARKVNEW JERSEY.

To all whom it may concern:

Be it known that I, CARL GUGGENBUEHLER, citizen of Germany, residing at Newark, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Tools for Facilitating the Adjustment of the Driving Shoes of,

Locomotives, of which the following is a specification.

This present invention has reference to tools for the adjustment of the driving shoes in the bearings of locomotives or the like relative to the driving boxes of the wheels, as described and shown in my Patent #1,327,468 dated January 6, 1920.

The construction of the tool of said patent has the drawback that it is only applicable to standard size locomotives. When the size of the lower edge of the bearing frame differs from the standard size my patented tool cannot be used.

The object of this improvement is to provide a construction which will allow an adjustment of the tool to fit differently sized locomotives.

With this object in view my invention consists in the novel construction, combination and arrangement of parts as will be hereinafter fully described and defined in the appended claims.

In the accompanying drawing in which similar reference characters denote corresponding parts, Fig. 1 is a side elevation of a part of the bearing frame of the locomotive, showing two of the driving shoes designed for one driving box clamped in position by my tool; Fig. 2 is a perspective view of my improved clamp; Fig. 3 is a perspective view of a detail of said clamp and Fig, 4 a section on line 4-4 of Fig. 2.

Referring specifically to the drawing (1 denotes the frame provided with the bearing Z) for the driving box (not shown) and the driving shoes 0. i

The clamp forming the subject of the present invention and serving for temporarily engaging the driving shoes 0 and hold them in position, while the locomotive is being lowered onto the wheels to place the driving box therein, consists of a hollow bar or block g, the upper face of which is shaped to conform with the usual shape of the lower Specification of Letters Patent.

TOOL FOR FACILITATING THE ADJUSTMENT OF THE DRIVING SHOES OF LCCOMOTIVES.

edge of the bearing frame, the said face be ing offset at one end to form a vertical shoulder g which will bear against the side of the downwardly projecting portion a of the bearing frame while the offset part 9 will bear against the lower face of the part a. The upper face of the block 9 is provided with a longitudinal slot 9 for the passage of the usual screw bolts (Z projecting from the lower edge of the bearing frame and generally serving for the fastening of the binder bars (not shown).

The block 9 is fastened to the frame by the screw bolts (Z, on which I apply specially constructed nuts 6 adapted to fit the usual two sizes of bolts (Z.

Thus far the construction of my tool is similar to the one described and shown in my aforenamed patent.

The improvement of the invention resides in that the end member 7' serving to support the driving shoes 0 when the tool is in position, instead. of being-directly applied to the block 9, as in the patent aforenamed, is attached to a member h which is slidably supported in the block g. To this end the offset portion 9 is provided with a longitudinal groove 9 in which the member h is slidably mounted. The forward end of said member 72. is provided with a cross groove h into which the reduced lower end j of the member j is adapted to be removably engaged. The rear end 7L of the slide it is cut out centrally and longitudinally to clear the opening g in the block 9 through which passes one of the screw bolts cl.

Equipped with this adjustable member h the tool at once becomes applicable to locomotives both of standard and irregular sizes. Thus, if the part a of the frame is longer than the length of the offset portion of the block then the slide 71- is adjusted to conform with the particular length of the part a. A set screw is working in a threaded bore 9 of the offset portion 9 serves to securely hold the slide h in its adj usted position.

That I claim and desire to secure by Letters Patent is:

A tool for facilitating the adjustment of the driving shoes'of locomotives as per claim 1, said tool including a block having an 0E- set portion to conform with and bear against the lower surface of the bearing "frame and WlllCh has openings for tlie free passage of the bolts projecting from the said frame, a

longitudinally sliclable member mounted in said offset portion, a vertical member removably engaged in said slidable member and serving to engage the lower edge of a
